32But he said to them, I have food to eat that you do not know about.
33So the disciples said to one another, Surely no one has brought him something to eat?
34Jesus said to them, My food is to do the will of him who sent me and to complete his work.
35Do you not say, Four months more, then comes the harvest? But I tell you, look around you, and see how the fields are ripe for harvesting.
